Dongle device for automatic pairing of payment terminal to mobile computing device

ABSTRACT

There are provided systems and methods for a dongle device for automatic pairing of payment terminal to mobile computing device. A merchant location may include one or more merchant devices used to provide sales to between the merchant and customers through generating transactions and processing payments. In this regard, the merchant devices may use connectable terminals that provide payment instrument processing. The connectable terminals may utilize a wireless connection with a merchant device and allow a user to provide their payment instrument, such as an EMV payment card, to the terminal to insert their payment information into a transaction. In order to pair the terminal to the merchant device, a dongle device may be added to the terminal to provide connection information to the merchant device for automatic pairing. The dongle device may also remove the connection information on removal or insertion of a new dongle device.

TECHNICAL FIELD

The present application generally relates to wireless pairing of processing devices, and more specifically to dongle device for automatic pairing of payment terminal to mobile computing device.

BACKGROUND

A merchant location may utilize mobile merchant devices to provide transaction processing with customers at the merchant location, for example, using tablet computers and handheld computing devices. These mobile merchant devices allow merchant employees to more easily process transactions when on the move between customers or when the customers may be mobile throughout the merchant location. These mobile merchant devices may require associated terminals to allow for entry of payment instrument information by a customer, such as a magnetic card reader and/or EMV card reader (e.g., a smart card having an embedded integrated chip according to the EMV standard or other technical standard). However, where these terminals may be wireless so that they may be handed over to a customer for the customer to enter a payment instrument and associated authentication (e.g., password, personal identification number (PIN), and/or signature), the terminals may be on and lose power. Thus, setup time between newly charged terminals may be cumbersome to employees to establish the wireless connection between the mobile merchant device and a new terminal. Moreover, if a terminal is misplaced and a new one quickly needed, changing connections between terminals may add additional time to transaction processing and cause customer dissatisfaction.

DETAILED DESCRIPTION

Provided are methods for dongle device for automatic pairing of payment terminal to mobile computing device. Systems suitable for practicing methods of the present disclosure are also provided.

A merchant may utilize a portable terminal that accepts payment cards for payment processing, such as a portable magnetic card reader or EMV card reader that may be brought directly to a user. Various merchant locations for merchants may provide one or more products, goods, or services (referred to herein as an “item” or “items”) for sale to users (e.g., customers). The merchant locations include physical merchant locations where the users may visit in order to select items for purchase and engage in a transaction to purchase the items. The merchant locations may include one or more merchants or merchant employees (referred to herein collectively as the “merchant” or “merchants”) that may assist the user in finding items, provide items to the user, and/or engage in a transaction with a user. The merchants may be mobile, and may have mobile merchant devices for transaction processing, such as tablet computers, handheld mobile devices, smart mobile phones, and other types of mobile communication devices. These devices may allow the user and merchant to establish a transaction and process the transaction using a payment instrument for the user. For example, the user may browse items at the merchant location, select one or more items for purchase, and visit a merchant to purchase the items through a transaction generated by the merchant's device. In other embodiments, the user may instead select items for purchase from the merchant, such as a restaurant, who may serve multiple users and be mobile between the users' locations.

In order to generate a transaction, the merchant may initiate a transaction using the communication device, for example, by entering items to a communication device for the user through scanning of item barcodes, selection of items on an interface of the communication device, entry of item identifiers, entry of item price, or otherwise providing transaction information to the communication device. The communication device may therefore correspond to a mobile device, such as a smart phone, which may include various features and components such as a display, input devices, processor, memory, network interface component for network communications. In various embodiments, the communication device further includes a RFID tag reader, a camera capable of scanning visual codes (e.g., QR or bar codes), and/or other devices for entry of item information to the communication device. The communication device may be used to process a transaction using an application executing on the communication device, such as a sales application associated with the merchant. For example, after receipt of an identifier for each of the one or more items for purchase and/or selection of the one or more items through an application interface of the mobile application, the communication device may generate a transaction for purchase of the selected item(s) by the user. Once the transaction is generated with associated costs (e.g., tax, tip, surcharges, etc.), the transaction may be ready for payment processing. However, in various embodiments, tip and other additional fees or payments may later be added by the user to the transaction during payment processing.

The merchant may require payment information from the user for processing of the transaction. For example, the user may provide a debit, credit, or other type of payment card (including gift cards and/or payment cards associated with an online payment provider, such as PayPal®) as a payment instrument to the merchant for payment of the transaction. In other embodiments, different payment instruments may be used, such as key fobs or other types of electronically readable payment instruments. Thus, the payment instrument (e.g., payment card) may include a non-transitory memory component that stores payment instrument information used during payment processing. In order to read the payment instrument and enter the payment instrument information (e.g., card number, expiration, backend processing pathway information, etc.), the merchant may require a terminal to read the data stored to the non-transitory memory of the payment instrument. For example, a terminal may correspond to a magnetic card reader and/or a smart card reader. A magnetic card reader may be utilized to read a magnetic strip disposed of on the payment instrument. Similarly, a smart card reader may correspond to an EMV smart card reader configured to receive information using RFID from a contact or contactless payment card having an embedded integrated circuit. With mobile communication devices used by the merchants, the terminal may also be wirelessly connected to the mobile communication device so that the terminal may be passed to a user for the user to swipe, insert, tap, or otherwise enter their payment card or payment card information to the terminal. Moreover, wireless terminals may provide additional security to users by allowing the user to more secretively and/or personally provide their personal identification number (PIN), password, and/or signature.

In this regard, the wireless terminals may be required to be wirelessly connected to respective merchant devices in order to provide payment processing between the wireless terminals and the merchant devices. The merchant devices and wireless terminals may wirelessly connect through WiFi, Bluetooth, Bluetooth Low Energy, LTE Direct, near field communications, radio, microwave, infrared, or other wireless communication protocol. Specific merchant device may connect with a specific terminal so that only those two devices send and receive data, such as payment instrument information used in a transaction processed with the merchant device. Thus, one to one pairing may be preferable to prevent incorrect transaction processing. If more than one terminal is connected to the merchant device, or more than one merchant device is connected to a terminal, then incorrect payment instrument information may be entered to a transaction and users may be incorrectly billed. However, as a merchant employee moves and separates from a wireless terminal and/or a wireless terminal loses power, maintaining the one to one connection between merchant device and wireless terminal may be difficult and/or cumbersome. Moreover, navigating through the merchant device interfaces to look up nearby devices for connection, determining available wireless terminals, physically identifying the wireless terminals, and connecting the devices may cause difficulties.

Thus, each wireless terminal includes a dongle device configured as at least a non-transitory memory for data storage as well as an integrated connection interface, such as a USB interface, a Micro-USB interface, Apple® Lightning® interface, or other type of connection interface. The dongle device may further include a processor, as well as applications for executing one or more processes with the dongle device. For example, in various embodiments, the dongle device may further include an input interface for receipt of a code, password, or other unlocking mechanism, as well as associated applications to allow use of the dongle device and terminal. In other embodiments, the dongle device may include a biometric detection device configured to provide biometric (e.g., fingerprint) processing and locking/unlocking. Further components may also be associated with the dongle device. The dongle device may include in the non-transitory memory at least connection information for the terminal. The connection information may include at least one connection parameter for use in connecting the merchant's communication device to the terminal. For example, a connection parameter may include a connection pathway (e.g., communication port addresses, a unique identifier for the terminal, other identifiers, etc.). Further connection parameters may specify a type of communication protocol (e.g., Bluetooth, WiFi, etc.) and/or communication protocol specifications. The connection information may further include executable processes, such as a process to load the connection parameter(s) to the merchant device and cause a connection to be established between the communication device and the terminal. However, in other embodiments, the process to load connection parameters and establish a connection may instead reside on the merchant's communication device, such as an application, plug-in to another application, operating system process, etc.

The dongle device may also be physically attached to the wireless terminal, such as through a cord, lanyard, extension cable, or other attachment mechanism. In other embodiments, the dongle device and the terminal may be associated through information or other process. When retrieving a terminal, the merchant may connect the dongle device directly to the communication device of the merchant. For example, the interface of the dongle device may be inserted to a matching input port of the communication device to accept the dongle device. Once connected, the connection information for the wireless terminal may be loaded to the merchant's communication device. The communication device may then execute a process to utilize the connection parameter(s) with connection protocol information for various connection protocols used by the communication device to establish a wireless connection between the merchant's communication device and the terminal. The wireless connection may the allow the communication device and the terminal to communicate, for example, to exchange keys for a secure communication session, transmit encrypted/unencrypted information, and/or process payments through transfer of payment instrument information.

Thus, after the communication device and the terminal are paired, and a transaction is entered by the merchant, the communication device may be ready to perform transaction processing. Where a total has not been calculated, the communication device may generate a total, as well as provide the total to the terminal for viewing by the user. The user may utilize the terminal to confirm the total and/or add a tip or other additional amount to the total. The user and/or merchant may also add any content to the transaction. When ready, the user may enter payment card information using features of the terminal, for example, by entering an EMV smart card to a reader of the terminal. The user may further be required to provide a PIN or an electronic signature. Once confirmed, the communication device may be ready to process the transaction with a backend financial institution to receive a payment to the merchant from the user.

The communication device may contact a backend payment processor, such as a credit provider, bank, online payment provider, or other financial institution to perform transaction processing. For example, the merchant may accept Visa®, Discover®, American Express®, PayPal®, and/or Venmo® at a specific merchant location when the user wishes to pay for a transaction. The communication device may provide the transaction information, such as a price or cost of the transaction, with the payment instrument information (e.g., a card identifier) and request payment to the merchant, for example, to an account for the merchant. The payment provider may then process a payment to the merchant using the user's payment account, the account of the merchant, and the transaction information. In various embodiments, a payment may not be processed where the payment provider cannot process the transaction, for example, where fraud is detect, if the user has insufficient funds, or other problem occurs during transaction processing. The merchant and/or payment provider may provide a transaction history to the user, such as a physical receipt where the user is required to sign in order to verify and record that the user authorized the transaction. The transaction history may also show a reason for denial or failure of processing the transaction, such as insufficient funds. The merchant and/or payment provider may also provide electronic receipts, which may be sent through text message, email, or other communications to an electronic account or device of the user for storage.

The merchant may remove the dongle device prior to, during, and/or after transaction processing. In certain embodiments, once the wireless connection between the communication device of the merchant and the terminal is established, the connection may be maintained until it is actively ended (e.g., closed through the communication device or terminal), a device runs out of power (which may only cause temporary loss of connection until power is restored), and/or the transaction finishes processing and/or the terminal become idle. In various other embodiments, when the merchant is finished with using the wireless terminal (e.g., after transaction processing), the merchant may remove the dongle device from the communication device. Once the dongle device is removed, one or more processes executed by the communication device may wipe and remove the connection parameter(s) for the connected terminal from the communication device, thereby severing the connection between the terminal and the communication device. In other embodiments, the connection may remain until a new dongle device is connected to the communication device. Once the new dongle device is connected, the previous connection parameters may be stored and/or deleted, while the new connection parameters for the new terminal supersedes the previous connection parameters and causes a new connection to the new terminal.

In other embodiments, the dongle device may instead be connected to a different device for pairing as described above two devices over a wireless connection. For example, the dongle device may instead be connected to an auxiliary component of a communication device system that may connect to the communication device system through wireless connections over a short range wireless communication protocol. In this regard, an auxiliary device may include wireless headphones, speakers, and/or microphones, as well as biometric sensing devices, wearable computing devices, and/or other types of connectable devices. In other embodiments, the connectable device may correspond to a console computing device of a vehicle, which may connect with a communication device using the dongle device, as described herein. Various other types of applications of the communication device may also receive data from or transaction data to the attached connectable device. For example, headphones and/or speakers may interface with a media playback application on the communication device, a console computing device may interface with a GPS and mapping application on the communication device, etc. The dongle device may also be used to pair the communication device with a secure wireless router, such as a password protected Internet router. The communication device may utilize an secure private network access application to access a secure private network provided by a secure wireless router.

FIG. 1 is a block diagram of a networked system 100 suitable for implementing the processes described herein, according to an embodiment. As shown, system 100 may comprise or implement a plurality of devices, servers, and/or software components that operate to perform various methodologies in accordance with the described embodiments. Exemplary device and servers may include device, stand-alone, and enterprise-class servers, operating an OS such as a MICROSOFT® OS, a UNIX® OS, a LINUX® OS, or other suitable device and/or server based OS. It can be appreciated that the devices and/or servers illustrated in FIG. 1 may be deployed in other ways and that the operations performed and/or the services provided by such devices and/or servers may be combined or separated for a given embodiment and may be performed by a greater number or fewer number of devices and/or servers. One or more devices and/or servers may be operated and/or maintained by the same or different entities.

System 100 includes a user 102 with a payment card 110, a terminal device 120, a merchant device 130, and a payment provider server 140 in communication over a network 150. User 102 may visit a merchant location for a merchant corresponding to merchant device 130. While at the merchant location, user 102 may select one or more items for purchase from the merchant, which may be entered to a transaction using merchant device 130. The merchant may utilize merchant device 130 for transaction processing with terminal device 120. Terminal device 120 may connect and synchronize with merchant device 130 using a dongle device connectable to merchant device 130. The dongle device may provide connection parameters to merchant device 130 and allow merchant device 130 to establish a wireless connection with terminal device 120. User 102 may then provide payment card 110 to terminal device 120 for communication to merchant device 130 and processing in the transaction. The transaction may be processed using payment provider server 140 to provide a payment to the merchant from user 102.

Terminal device 120, merchant device 130, and payment provider server 140 may each include one or more processors, memories, and other appropriate components for executing instructions such as program code and/or data stored on one or more computer readable mediums to implement the various applications, data, and steps described herein. For example, such instructions may be stored in one or more computer readable media such as memories or data storage devices internal and/or external to various components of system 100, and/or accessible over network 150.

User 102 may utilize payment card 110 to provide a payment to a merchant associated with merchant device 130, for example, during processing a transaction to pay for one or more items in the transaction. In this regard, payment card 110 may correspond to a payment instrument associated with a financial account that includes held funds, credit, investments, and/or other types of financial security or instrument used to provide payments to another party from user 102. Thus, payment card 110 may be associated with a financial instrument of user 102 and may utilize the financial instrument to provide payment on behalf of user 102. For example, payment card 110 may be associated with a payment account, available credit, and/or bank account held, serviced by, and/or accessible to payment provider server 140. In other embodiments, payment card 110 may correspond to another financial institution. Payment card 110 may be processed by payment provider server 140 to provide a payment to the merchant associated with merchant device 130 from user 102.

Payment card 110 may further include a storage component for storing payment instrument information, such as information for payment card 110. For example, a magnetic strip may store information for payment card 110, such as a cardholder name (e.g., name for user 102), the account number for payment card 110 and/or the associated account utilized when processing payment card 110 to provide payments, the expiration date of payment card 110, and/or the card security code or card verification code of payment card 110 (e.g., a number associated with the card and normally found on the back of the card near a signature line). In various other embodiments, payment card 110 may correspond to an EMV (e.g., Europay®, MasterCard®, Visa®) or other smart card having an embedded integrated chip storing information utilizing the EMV standard or other technical standard. In such embodiments, payment card 110 may be a contact (e.g., inserted) card or a contactless (e.g., read through NFC or other short range wireless protocol) card, and may include similar information to a magnetic strip (e.g., cardholder name, account number, expiration date, and security code). Payment card 110 may be utilized with terminal device 120 to provide payments to the merchant associated with merchant device 130, as discussed herein.

In various embodiments, user 102 may further have a communication device, such as a mobile smart phone, tablet computer, or other type of mobile communication device in possession of user 102 at a merchant location. The communication device may include a payment application, which may be configured to interact with payment provider server 140 to perform various transactions and transaction review. For example, the communication device may receive the results of transaction processing, which may include the use of payment card 120, and may display the result to user 102 and/or store the results for later review. Thus, the payment application may include or be associated with a payment account and/or digital wallet for user 102 with payment provider server 140. The payment application may further provide one or more interfaces for display of received transaction information, for example, a transaction between user 102 and the merchant associated with merchant device 130. The transaction may be received from merchant device 130 and displayed to user 102 for review prior to providing payment using payment card 110. In other embodiments, the communication device may include additional or different modules having specialized hardware and/or software as required.

Terminal device 120 may correspond to a hardware device normally associated with a point of sale device or other type of device that engages in transactions using payment instrument input read by terminal device 120. In this regard, terminal device 120 may correspond to a standalone device connectable to at least one other communication device for payment processing, such as merchant device 130. Terminal device 120 may include hardware and software for wireless communications with another device, such as merchant device 130, over a communication protocol. In various embodiments, the communication protocol may correspond to near field communication, Bluetooth communication, Bluetooth Low Energy (BLE) communication, WiFi communication, and LTE Direct communication. Terminal device 120 may further have connection parameters used to connect with terminal device 120, such as a communication port identifier, name, wireless connection address, or other identifier used in identification of and connection to terminal device 120. Such information may be stored to a database of terminal device 120. Moreover, the aforementioned information may be stored to dongle device 124, for example, by a manufacturer of terminal device 120, by terminal device 120 itself, and/or by an administrator configuring terminal device 120 with dongle device 124. Additionally, the communication module or interface of terminal device 120 may be used to communicate read payment instrument information, such as data from a payment card, to a connected device (e.g., merchant device 130).

Additionally, terminal device 120 of FIG. 1 contains a payment card reader 122 and a dongle device 124. Payment card reader 122 and dongle device 124 may correspond to devices having executable processes, procedures, and/or applications with associated hardware. In other embodiments, terminal device 120 may include additional or different devices as required. For example, although terminal device 120 is described as being used in payment processing and having payment card reader 124, in other embodiments, terminal device 120 may correspond to other device accessories and auxiliary components, including Internet routers, speakers, a microphone, a biometric detector, headphones, vehicle console devices, or other connectable computing devices.

Payment card reader 122 and dongle device 124 may correspond to one or more devices used to provide payment processing by connecting terminal device 120 to merchant device 130, reading data stored to a non-transitory memory of payment card 110, and providing payment instrument information to merchant device 130 from terminal device 120 using the connection.

For example, payment card reader 122 may include hardware and associated software to read data stored to a storage medium of payment card 110. The data stored to the storage medium of payment card 110 may include payment instrument information, such as a cardholder name (e.g., name for user 102), an account number for payment card 110, an expiration date of payment card 110, and a security code for payment card 110. The storage medium may correspond to a non-transitory memory, which may include a magnetic strip disposed of on a card surface, an integrated circuit chip (e.g., an RFID chip) inserted into the body of payment card 110, and/or another type of memory unit, such as an RFID tag within a key fob. Thus, payment card reader 122 may correspond to a magnetic card reader capable of reading magnetic strips and/or a smart card reader, which may be capable of reading EMV standard or other technical standard smart card chips using a contact or contactless reader. Once payment card reader 122 has the payment instrument information retrieved from payment card 110, payment card reader 122 may utilize the wireless communication capabilities (e.g., a communication module and associated hardware and software for wireless communications over a communication protocol) to transmit the payment instrument information to merchant device 130 over a wireless connection between terminal device 120 and merchant device 130.

Dongle device 124 may correspond to a separate hardware device physically connected to or otherwise associated with terminal device 110. For example, in one embodiment, dongle device 124 may be connected using a lanyard, cord, extendable cable, or other connection mechanism. However, in other embodiments, dongle device 124 and terminal device 120 may be paired using other association mechanisms, such as numbering, names, color, shape, or other physical property. Dongle device 124 may appear and function similar to a USB flash drive having at least a memory and a connection interface capable of physically connecting to an input port of merchant device 130. Thus, dongle device 124 may include a database stored to a non-transitory memory and may store the connection information for terminal device 120 having at least one connection parameter for use in establishing a connection between terminal device 120 and merchant device 130. Thus, once dongle device 124 is connected, the connection information may be automatically loaded to merchant device 130 and cause the connection parameter(s) to configure merchant device 130 to establish a wireless connection between terminal device 120 and merchant device 130. In this regard, the database of dongle device 124 may further store one or more processes to automatically execute on connection to merchant device 130 and cause the connection information to be established with merchant device 130 and configure a communication module 138 of merchant device 130 to connect to terminal device 120. In various embodiments, in order to execute the processes and configure communication module 138 of merchant device 120 to connect with terminal device 120 automatically, dongle device 124 may further include processors and associated software necessary to establish and execute the processes. Dongle device 124 may provide processes only to configure merchant device 130 for a connection with terminal device 120. However, in other embodiments, dongle device 124 may also provide a process to clear the connection information and associated processes from merchant device 130 on detection that dongle device 124 is removed from merchant device 130 (e.g., disconnected). Moreover, dongle device 124 may further include additional features, such as authentication hardware and software, to only allow authenticated users to utilize dongle device 124 to wireless connect terminal device 120 to the device physically connected to dongle device 124. For example, an input interface may require an alphanumeric password, a biometric scan (e.g., fingerprint), or other authentication mechanism.

Merchant device 130 may be maintained, for example, by a merchant at a merchant location corresponding to merchant device 130, which may offer one or more items for purchase at the merchant location. In this regard, merchant device 130 include one or more processing applications which may be configured to interact with terminal device 120 and/or payment provider server 140 to facilitate generation of a transaction and payment to the merchant for the transaction. In various embodiments, merchant device 130 may also correspond to devices offering online sale of items, which user 102 may purchase while at a merchant location. However, in other embodiments, merchant device 130 may be maintained by or include any merchant, including merchants that offer offline sales of items through a merchant location. Merchant device may be implemented as a personal computer (PC), telephonic device, a smart phone, laptop/tablet computer, wristwatch with appropriate computer hardware resources, eyeglasses with appropriate computer hardware (e.g. GOOGLE GLASS®), other type of wearable computing device, implantable communication devices, and/or other types of computing devices capable of transmitting and/or receiving data, such as an IPAD® from APPLE. Moreover, although only a single merchant device is referenced herein, a plurality of merchant devices may function similarly.

Merchant device 130 of FIG. 1 contains a sales application 132, other applications 134, a database 136, and a communication module 138. Sales application 132 and other applications 134 may correspond to processes, procedures, and/or applications executable by a hardware processor, for example, a software program. In other embodiments, merchant device 130 may include additional or different modules having specialized hardware and/or software as required.

Sales application 132 may correspond to one or more processes to execute modules and associated specialized hardware of merchant device 130 that provides a sales interface to sell one or more items offered by a merchant (not shown) associated with merchant device 130, and further provide payment processes for a transaction to purchase the items for sale from the merchant corresponding to merchant device 130. In this regard, sales application 132 may correspond to specialized hardware and/or software of merchant device 130 to provide a convenient interface to permit a merchant offer items for sale. For example, sales application 132 may be implemented as an application offering items for sale that may be utilized by the merchant or a merchant employee to enter items selected by a user to a transaction, determine a total cost for the transaction, and initiate a checkout and payment process for the transaction. The checkout and payment process may require a payment instrument to be proffered by user 102 for use in the transaction. The payment instrument may be processed, as discussed herein, in order to provide a payment for the transaction and complete transaction processing. However, in order to provide transaction processing through terminal device 120, sales application 132 may be required to connect with terminal device 120, for example, through the use of dongle device 124 to receive connection information for terminal device 120.

Thus, sales application 132 or another connectivity application of merchant device 130 may include processes to establish a connection with terminal device 120 using received connection information. In various embodiments, the processes may be provided by dongle device 124, as discussed herein, which may remain on merchant device 130 for a limited time (e.g., an amount of time, until the connection is severed, and/or until dongle device 124 is removed from merchant device 130). On detection of dongle device 124 connecting to an input port of merchant device 130, sales application 132 and/or the other application or processes may receive or access connection information from dongle device 124 for terminal device 120. The connection information includes at least one connection parameter for use with a communication protocol to establish a wireless connection between terminal device 120 and merchant device 130. The connection information may configure the connection settings of communication module 138 of merchant device 130 to establish a connection with terminal device 120. For example, the connection information may include an identifier for terminal device 120 and cause merchant device 130 to search for the identifier from receivable local broadcasts of identifier names and/or requests to establish a connection (e.g., search for nearby available devices having a Bluetooth connection channel available). The connection information and associated processes may therefore cause terminal device 120 and merchant device 130 to pair for purposes of transaction processing. The processes may execute in the background and/or without input from the merchant utilizing merchant device 130. For example, the process may automatically execute on connection of dongle device 124 so that further input is not required from the merchant to merchant device 130. Moreover, the merchant may be alerted through a notification in sales application 132, a toolbar, a connections icon, or other interface component when the connection between terminal device 120 and merchant device 130 is established.

Sales application 132 may include information for a price for the item, a discount for the item, a price change for the item, and/or other incentives for items and/or with the merchant corresponding to merchant device 130 (e.g., rebates, payments, etc.). Once the transaction is generated and terminal device 120 is communicating with sales application 132 through a wireless connection with merchant device 130, sales application 132 may be ready for transaction processing to receive a payment. Sales application 132 may receive payment instrument information for payment card 110 from terminal device 120 using payment card reader 122. Sales application 132 may utilize the payment instrument information with transaction information to process the payment, for example, by communicating the aforementioned information with additional merchant information to a payment processing system, such as payment provider server 140. Payment provider server 140 may then process the information and provide a payment to the merchant, as discussed herein. In such embodiments, once a payment is processed for a transaction, for example, by having payment provided to the merchant account, notification of payment (or failure, for example, where there are insufficient user funds) may be sent to sales application 132. The payment may be made by payment provider server 140 on behalf of user 102 associated with payment card 110. Sales application 132 may then receive the results of the transaction processing, and complete the transaction with user 102, for example, by providing a receipt for the transaction and/or allowing user 102 to purchase the items and remove the items from the merchant location.
